Hund txoj cai hais tias yog tias 2 lossis ntau dua degenerate (piv txwv li tib lub zog) orbitals muaj, ib qho hluav taws xob mus rau hauv ib qho kom txog thaum tag nrho lawv ib nrab puv ua ntej ua khub. Cov Pauli Exclusion Txoj Cai hais tias tsis muaj ob lub tshuab hluav taws xob tuaj yeem txheeb xyuas los ntawm tib pawg ntawm quantum tooj.
Tsis tas li ntawd, Hund txoj cai nrog piv txwv yog dab tsi?
Hund txoj cai hais tias: Txhua lub orbital nyob rau hauv asublevel yog singly nyob ua ntej ib qho orbital yog doubly nyob. Tag nrho cov electrons nyob rau hauv singly occupied orbitals muaj tib spin (kom ua kom tag nrho cov spin).
Tsis tas li ntawd, Pauli exclusion txoj cai piv txwv yog dab tsi? Piv txwv ntawm Pauli ExclusionPrinciple Cov kev cais tawm lees paub tias txhua lub tshuab hluav taws xob hauv ib qho atom argon yog nyob rau hauv ib lub xeev tshwj xeeb. Lub 2s levelelectrons muaj tus lej quantum sib txawv rau cov neeg nyob hauv 1s orbital. Cov khub ntawm 2s electrons txawv ntawm ib leeg vim lawv muaj qhov sib txawv.
Kuj paub, Hund txoj cai yooj yim txhais yog dab tsi?
Hund txoj cai . Hund txoj cai : Txhua lub orbital ina subshell yog singly nyob nrog ib tug electron ua ntej ib qho orbital yog ob zaug nyob, thiab tag nrho cov electrons nyob rau hauv singly occupiedorbitals muaj tib lub kiv.
Leej twg tsim Hund txoj cai?
Friedrich Hund [Friedrich Hermann Hund] yog ib tug Germanphysicist yug thaum Lub Ob Hlis 04, 1896 - tuag rau lub Peb Hlis 31, 1997. Hund tau ua qhov tseem ceeb rau txoj kev xav quantum. Hunddiscovered lub thiaj li hu ua tunnel nyhuv los yog quantum tunneling thiab Hund txoj cai ntawm qhov siab tshaj plaws multiplicity.

Dab tsi yog qhov txawv ntawm txoj cai khoom thiab txoj cai saw?
Peb siv txoj cai saw thaum sib txawv ntawm 'kev ua haujlwm ntawm kev ua haujlwm', zoo li f(g(x)) feem ntau. Peb siv txoj cai khoom thaum sib txawv ntawm ob txoj haujlwm sib npaug ua ke, zoo li f(x)g(x) feem ntau. Tab sis nco ntsoov lawv yog cov haujlwm cais: ib tus tsis vam khom rau cov lus teb rau lwm tus
Txoj cai lij choj ntawm Kev ywj pheej Assortment piav qhia nrog piv txwv yog dab tsi?
Txoj cai ntawm kev ywj pheej assortment yog nyob ntawm tus ntoo khaub lig dihybrid. Nws hais tias qhov qub txeeg qub teg ntawm ib tus cwj pwm yeej ib txwm muaj kev ywj pheej ntawm qhov qub txeeg qub teg ntawm lwm cov cim hauv tib tus neeg. Ib qho piv txwv zoo ntawm kev ywj pheej assortment yog Mendelian dihybrid ntoo khaub lig
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
